..Whole-head magnetic recordings located the source of this native-language, phoneme-related response enhancement, and thus the language-specific memory traces, in the auditory cortex of the left hemisphere...

..The discrepancy between the results obtained with and without focal attention suggests that illusory conjunctions may occur during voluntary access to the preattentively encoded object representations...

..To test the statistical learning skills at birth, we recorded event-related brain responses of sleeping neonates while they were listening to a stream of syllables containing statistical cues to word boundaries...

..The present results suggest that automatic duration discrimination in audition operates even for durations of the order of seconds; yet its optimum time scale might be of the order of milliseconds...

..Moreover, differences in ERP amplitudes and in their correlations with the reaction times between younger (7-10 years) and older (11-13 years) children indicated developmental changes in attentional brain functions...

Atypical pattern of discriminating sound features in adults with Asperger syndrome as reflected by the mismatch negativity

..The neural abnormalities that underlie such deficits in alcoholics were explored with event-related potential (ERP) components that disclosed different phases of detection and orienting to stimulus changes...

..This suggests that children with autism lose their advantage in phoneme discrimination when the context of the stimuli is speech-like and requires abstracting invariant speech features from varying input...

Speech- and sound-segmentation in dyslexia: evidence for a multiple-level cortical impairment

..This pattern parallels known behavioural differences between children with these cleft types. Brain responses to rare sounds, in contrast, had no differentiative power with respect to the cleft type...

Electrophysiological evidence for cross-modal plasticity in humans with early- and late-onset blindness

T KujalaDepartment of Psychology, University of Helsinki, FinlandPsychophysiology 34:213-6. 1997

..These results suggest that cross-modal reorganization may occur even in the mature human brain...

The processing of sound duration after left hemisphere stroke: event-related potential and behavioral evidence

..This result, obtained both by behavioural and neural indices at attentive and automatic levels of processing, indicates precise feature-specific tuning of the auditory-cortex functions by the mother tongue...

..The results suggest that both MEG and EEG can be used for investigating the simultaneous activity of the left and right auditory cortices independently, MEG being superior in certain experimental setups...

Cortical auditory dysfunction in children with oral clefts: relation with cleft type

..The present results suggest that the post-withdrawal brain hyperexcitability in the alcoholic brain, gradually recovering with abstinence, could be objectively and non-invasively studied with the MAEP...

..These findings were predominant over the right cerebral hemisphere. These results show impaired neurobiological basis for speech-prosody processing at an early, pre-attentive auditory discrimination stage in AS...

..Moreover, the fact that the present training effects were obtained by using a program including no linguistic material indicates that dyslexia is at least partly based on a general auditory perceptual deficit...

..The first negative wave peaked at about 150 msec and the second at about 350 msec after the change onset. At least one negative deflection, which was interpreted as evidence for stimulus change-detection, was observed in every infant...

The processing of speech and non-speech sounds in aphasic patients as reflected by the mismatch negativity (MMN)

..8). The harmonical tones elicited MMN and P3a with shorter latencies and larger amplitudes, than did pure sinusoidal tones in all frequency bands. The results may have implication to pitch-perception theories...

..We sought to determine the recovery of cortical auditory discrimination in aphasic, left-hemisphere-stroke patients by using an electrophysiological response called mismatch negativity (MMN) and speech-comprehension tests...

No effects of mobile phone use on cortical auditory change-detection in children: an ERP study

..The double-deviant MMNs were found to be additive but the triple-deviant MMN was clearly underadditive. The results suggest complex interactions between brain processes involved in analyzing several simultaneous deviant features...

Instrumentation for the measurement of electric brain responses to transcranial magnetic stimulation

..The experimental results bear out the prediction that MMN is due to both adaptation and lateral inhibition. Finally, we suggest that MMN might serve as a probe of what stimulus features are mapped by human auditory cortex...

..In summary, the present results support the existence of pre-perceptual integration mechanism of 100-200 ms duration and emphasize its importance in switching attention towards the stimulus change...

The mismatch negativity in evaluating central auditory dysfunction in dyslexia

..Furthermore, the MMN holds promise of showing plastic changes in the brain of dyslexic individuals underlying the alleviation or remediation of dyslexia in the course of a successful training programme...

..In the present study, we tested whether the MMN can be recorded even without the standard stimulus, with the invariant properties of the deviant stimuli serving as a standard against which to detect the sound changes...

Auditory discrimination profiles of speech sound changes in 6-year-old children as determined with the multi-feature MMN paradigm

..Similar MMNs in the two paradigms would suggest that they tap the same processes. This would promote the usefulness of the more time-efficient multi-feature paradigm for future studies in children...

Training the brain to weight speech cues differently: a study of Finnish second-language users of English
